I just use dd -ip /dev/sda -op /dev/sdb
to clone my old disk to new disk, and boot from my new disk.
All the things remain the same except that applications in Launcher changed back to default.
Why? And I cannot unlock from Launcher and lock to Launcher, it sucks, any help?

I found that answer. But to be more helpfule, i will show you how to debug it.
- Since it's something related to Launcher, And i don't know how does Launcher work, so i just need to find something related to Launcher. Which is
Appearance
in Dash.(I found this by Google). - Under
Behavior
tab, I can't change everything, i can click the checkbox, but nothing happen. - So, now i think there should be some output information in terminal. So i need to know how to open
Appearance
in terminal - Found
Appearance
in/usr/share/applications
, the command isunity-control-center appearance
- Type
unity-control-center appearance
in Terminal. And do the same thing as step 2. Terminal show output like this:dconf-WARNING **: failed to commit changes toconf:GDBus.Error:org.gtk.GDBus.UnmappedGError.Quark._g_2dfile_2derror_2dquark.Code17: Cannot open dconf database: invalid gvdb header
- Of course i don't know what the hell it is. But i now get some new key word to search on the Google! Yeah! I searched
Cannot open dconf database: invalid gvdb header
- And I found solution, just remove
~/.config/dconf/
(Of course backup first)

.desktop
files in theIcon=
-line. These.desktop
files are stored in/usr/share/applications
(globally) and/or in~/.local/share/applications
(locally). If they exist in both (for the same application), the local ones overrule the global ones. – Jacob Vlijm Feb 16 '15 at 14:52/home
or other directories, or just/
andswap
)? – Byte Commander Feb 16 '15 at 16:04sudo parted -l
)? Or maybe it lost somehow the link to the /home partition (maybe different UUID does not match the one in /etc/fstab - don't know how a dd-clone would look like according to this) – Byte Commander Feb 16 '15 at 17:16/usr/share/applications
will show on the Launcher right? – demonguy Feb 18 '15 at 13:26
